I have moved to another country with a new SIM card in my same phone and can no longer identify one of my old contacts with iMessage, and can't see new photos in a stream of hers I subscribe to. Other apple users, no problem, but this I can't get to work!
We've both removed each other as contacts and tried to text again, but messages just arrive to her, not back to me. She can see new pics I post but I can't see hers. I'm guessing her phone tries to contact me in my old number, how do we make it forget that?
